Astronomers at Lowell Observatory have one of the first instruments capable of detecting Earth-sized exoplanets outside our solar system.

Some scientists who study Mars also study Northern Arizona. That’s because our lava fields and water-carved canyons are similar to Martian terrain. It’s a good place to test out whether future colonists on Mars would be able to build houses out of local materials. That’s what astronomer Antonio Paris of St. Petersburg College in Florida is doing. He’s traveling the Colorado Plateau collecting soil samples to see if they’ll make good cement. He told KNAU’s Melissa Sevigny, if works here, it might also work on Mars.

About 30 miles northeast of Flagstaff in a remote area of high desert, is a set of manmade craters blasted into an ancient lava flow. They were put there 50 years ago as a training site for astronauts preparing to walk and drive on the moon.

Nearly 120 meteors an hour streamed across the sky earlier this month during the Geminid meteor shower. It’s considered one of most entertaining celestial events for Earthlings because the meteors are so bright and abundant. Writer Scott Thybony decided to view the show from a prehistoric—but undisclosed—site where an ancient meteorite is buried. He has more in his latest Canyon Commentary.
